self inflating tyres

The tyre, awarded “best breakthrough” by US magazine Popular Mechanics, maintains the correct pressure via a valve mounted inside the tyre – but which pokes through a gap in the tread.

As the tyre rolls, the deformation of the tyre flattens the tube, pushing air through an inlet valve. Air is released – or sucked in – as required.

Although it will be on North American roads in trial conditions next year, it’s not likely to be available in Australia until 2014 at the earliest.

“The concept has been tested and it works, we’re now just looking at bringing it to market,” says James Peate, communications manager at Goodyear Australia.

“There would be a price premium but it’s too early to estimate what it would cost.”

So can you adjust the regulator to whatever PSI you want? seems like it'll be an internal thing and you'll have to buy 36psi-40psi tyres... lol.

nice idea, but i think i`ll wait for them to be around a few years and get any bugs out of them before i go looking for them.
